UNITED STATES ALBERT FENIMORE ROCKYVELL, OF BRISTOL, CONNECTICUT, ASSIGNOR TO THE NElV DEPARTURE BELL COMPANY, OF SAME PLACE.

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 581,306, dated April 27, 1897.

Application filed August 24, 1896.

To all whom it may concern."

Be it known that I,. ALBERT FENIMORE ROCKWELL, of Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bell Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of my invention is to provide a revoluble striker-mount for a gongbell. Such carrier-mounts are already known in the art, but serious objections to prior constructions have existed in the expense and labor made necessary in their construction, the great difficulty in avoiding rattling and noise in operation without interfering with their smooth, easy, and effective action, and the seeming impossibility of insuring uniformity in manipulation and effect.

To the end of overcoming these and other difficulties and of meeting the requirements for a successful revoluble striker-mount, my invention consists in the details of the several parts of such a mount and their combination in the striker-mount of a bell, as is hereinafter more particularly described,and pointed out in the claims.

Reference is to be had to the annexed d rawings, and to the figures marked thereon, forming a part of this specification, the same figures designating the same parts or features wherever they occur.

Referring to the drawings, Figure 1 is a perspective View of the striker-mount. Fig. 2 is a plan View looked at from above. Fig. 3 is a side view of the spring. Fig. 4 is a side view of the striker-mount in section. Fig. 5 is a perspective view of the striker as herein shown. Fig. 6 is a side View of the strikermount without top plate, spring, or strikers. Fig. 7 is a plan view from above of the top plate. Fig. 8 is a perspective view of the washer.

In the accompanying drawings, 1 designates the striker, which, as herein shown, is made of metal, rounded, with a central aperture for loosely pivoting it to a rotating hand.

2 is a cylinder adapted to be carried loosely on a post fixed to the base-piece of the bell for Serial No. 603,810. (No model.)

the pu rpose and provided at its lowerend with a pinion to mesh with a train of gear-wheels provided to actuate the striker-mount. The cylinder projects slightly above the top plate of the striker-mount.

4 is the bottom plate of the striker-mount, fixed rigidly to the cylinder 2. At a short distance from each end of the plate pins 9 and 9 are riveted into the plate, which are provided at their upper ends with heads l0 l0.

5 is the top plate of the strikermount and has an orifice at 6 to fit over the cylinder 2, and eyes 11 11 are out in the plate near the ends, with enlargement-s toward the center of the plate. These eyes fit over the pins attached to the bottom plate in such a way that the heads of the pins confine the plate by bearing on the narrower parts of the eyes. By slipping the plate off the central cylinder the plate can be moved from one side to the other and detached from the pins by passing it off the pins through the enlargements of the eyes.

The pins 9 9 carry the strikers 1. Above and below each striker is placed a thin washer 12, which Icut out of vulcanized fiber. These washers assist in avoiding danger of rattle and noise. The strikers are usually made of cast-iron or hard metal and the plates of brass. Without the washers the iron wearing against the brass polishes the latter and prevents the friction which is very desirable for the per .fect operation of the bell.

13 is a spring with its two arms bent upward, as shown in Fig. v3. It has a central aperture to fit over the cylinder 14, and its ends are forked to engage the heads of the pins 10 10.

The operation of the device is now apparent. The strikers are carried on the bottom plate and limited in motion by the pins. The top plate confines them to the pins, and the spring maintains a constant, true, and even tension on each arm of the top plate by the reason that the spring has its bearing in the center.

All rattling and noise are avoided and an even effective result is secured without a resort to means to confine the striker-mount, which will produce great friction and make manipulation laborious and difficult.

Such a striker-mount as I here describe is peculiarly adapted for use in a bell similar to that shown and described in Letters Patent No. 471,982, granted to Edward Dayton Rockwell March 29, 1892, but there are many other mechanisms for operating the strikermount to which it is equally well adaptad.

I would not confine myself to the exact features as herein described in all particulars. For example, instead of the cylinder 2, which is intended to revolve on a post, a post may be used journaled into a collar in the base of the bell. So the strikers may be of: various forms. The essence of my invention resides in the peculiar mechanism whereby in the use of the spring in connection with the top plate I secure, by the simplest and cheapest means yet devised, noiseless, uniform, and efficient action.

I claim as my invention the following-described novel features, namely:

1. In the striker-mount of a bell of the character described the curved spring with arm's bent outward, their ends bearing up against the pivot-heads, its center being loose on the post and bearing on the top plate of the strikermount, keeping the top plate in position without other support, substantially as hereinbefore described and set forth.

2. In bell mechanism, astriker-mount comprising in its construction the revolving spindie or cylinder, a bottom plate secured thereto provided with pins having heads at their extremities, strikers loosely mounted on said pins, a top plate loosely mounted on the cylinder and having apertures through which said pins proj ect,and a spring loosely mounted on the cylinder and having two arms bent upward, the extremities of the arms engaging the under side of the heads of the pins, and bearing upon the top plate, whereby the top plate is made to exert an even pressure upon the strikers, holding them on their pivots and preventing rattling, substantially as hereinbefore described and set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ALBERT FENIMORE ROCKWELL.
